PORTABLE ROOF.

SPECIFICATION forming part of Letters Patent No. 349,887, datedSeptember 28, 1886.

Application filed January I3, 1886. Serial No. 189,742. (No model.)

To all whom it may concern:

Be it known that I, CLARK MOEUING KEEL- ER,0fHaSki11S,i11 the county ofWood and State of Ohio, have invented a new and useful Improvement inPortable Roofs,of which the fol.- lowing is a specification, referencebeing had to the annexed drawings, forming a part thereof, in which-Figure 1 isa side sectional elevation. Fig. 2 is a vertical transversesection taken online a a: in Fig. 1.

Similar letters of reference indicate corresponding parts in thedifferent figures of the drawings.

The object of my invention is to provide for the use of farmers andout-of-door workmen an easily-constructed portable roof which may bereadily adjusted to various heights.

My invention consists in avertical post provided with feet andbraces,andin aroofformed of separable timbers and boards arranged toslide up and down on the posts, and in means for raising and loweringthe roof and holding it at the desired elevation, as hereinafter morefully described.

The posts A are provided with tenons a upon their lower ends, which arefitted in the slot bin the sills or feet B, which sills, as shown, areformed of planks B, spaced by the tenons a and braces C, hereinafterdescribed, and fastened together by the bolts 1); but these sills may besolid sticks mortised for the posts and braces.

The braces O, secured in the sills B, enter notches c in opposite sidesof the post A, and keep the posts A at right angles with the sills B. Inthe upper ends of the posts are formed mortises d, in which arejournaled sheaves c. The posts A are provided at their tops with caps f,and upon opposite sides of the posts, near the braces C, are securedcleats g, the caps f and cleats 9 serving to limit the movement of theroof.

The ridge-pole D is formed of two parallel beams, h, with interveningdistance-pieces, t, whose width is a little greater than that of theposts A. The posts A are received between the beams h, forming theridge-pole, and out side of the posts and between the ends of the beamsh are journaled rollers j, which bear upon the outer sides of the postsA,and which admit of moving the ridge-pole D up and down when the postsA are subjected to outward pressure.

On each post A,on the outer side thereof, and near the lower end, issecured a Windlass, E, of the ordinary description, which is providedwith a hand-crank, k, by which it may be operated. Ropes ZeXtendfrom-thewindlass over the sheaves e, and are attached to eyes at,secured to the distance-piecesi in the ridge-pole D. Between the beamsh, forming the ridgepole D, are pivoted the braces F upon bolts n,passing through the'beams h and the braces, and the free ends of thebraces are beveled to adapt them to enter notches 0, formed in the postsA. By meansof the braces F the ridgepole D is held at any desiredheight, and is also braced. A frame formed of side bars, G, and endbars, H, is arranged to slide between the 'posts A, and is provided withcleats 1), which guide them along the posts A.

The roof-boards I J are provided with cleats g at opposite ends, thecleats upon the upper ends of the roofboards projecting downward, andthe cleats upon the lower ends of the roofboards projecting upward. Theroof-boards I J alternate with each other, so as to break joints andprevent the rain from leaking through. The downwardly-projecting cleatsq of the lower roof-boards, J, are hooked over the upper edges of thebeams l1, forming the ridge-pole, and the upper edges of the beams arebeveled to conform to the pitch of the roof. The cleats q of the upperroof-boards, I, are hooked over the ends of the lower roof-boards, J.The lower roof boards, J, at the ends of the roof are provided withL-shaped cleats 1', which cngagethe side bars, G. A ridge-piece, K,formed of the boards 8, secured together at the proper angle, completesthe roof.

My improved portable roof constructed in this manner may be adapted toany height of stack, and may at any time be raised or lowered. Theroof-boards may be readily applied or removed, so that the stack whichis to be formed under the roof may be built by means of a horsehay-fork.

If desired, the posts A may be made hollow of boards nailed together,when the pulleys may be placed inside of the posts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters I Patent, is n 1. In a portable roof, the combinationof the 5 posts A, sills B, braces O, ridge-pole D,braces F, the frameformed of the end bars, H, andside bars, G, the roof-boards I J havingcleats (1 upon opposite ends and provided with cleats r, for engagingtheside bars, G, and means for :0 raising and lowering the roof,substantially as herein specified.
